Nonlinear optical crystal barium methanesulfonate as well as preparation method and application thereof

The invention relates to a novel photoelectron functional material and a growth method and application thereof, in particular to a nonlinear optical crystal barium methanesulfonate and a preparation method and application thereof, the chemical formula of the barium methanesulfonate crystal is Ba (SO3CH3) 2, the nonlinear optical crystal is an orthorhombic crystal system, the space group of the crystal is Cmc21, and the space group of the crystal is Cmc21. And the cell parameters are alpha = beta = gamma = 90 degrees. The powder frequency-doubled effect of the barium methanesulfonate crystal disclosed by the invention is 1.2 times that of KH2PO4 (KDP). Therefore, the barium methanesulfonate nonlinear optical crystal has better phase matching capability.

Remote attestation method and device based on alliance chain, electronic equipment and storage medium

The invention provides a remote attestation method and device based on an alliance chain, electronic equipment and a storage medium. The remote attestation method based on the alliance chain comprises the steps that an external node sends an attribute certificate application packet to a third-party trusted institution; the external node receives an attribute certificate of the third-party trusted institution, wherein the attribute certificate is generated by the third-party trusted institution according to the attribute certificate application packet; the external node sends a network access request to a consensus node in the alliance chain system, wherein the network access request comprises an attribute certificate; and if the consensus node verifies that the sum of validity of the network access request is passed, the external node becomes a trusted node in the alliance chain system. According to the trusted network access method oriented to the alliance chain provided by the invention ...

File processing method and device, electronic equipment and storage medium

The invention relates to the field of information security and trusted computing, and provides a file processing method and device, electronic equipment and a storage medium, and the method comprises the steps: receiving a file processing instruction, and determining a first execution metric corresponding to the file processing instruction; comparing the first execution metric with a metric reference value of a metric reference library in the USB Key; and if it is determined that the first execution metric is consistent with the metric reference value, encrypting/decrypting a file corresponding to the file processing instruction to obtain a target file. According to the application, the process of encrypting and decrypting the file can have the capabilities of detecting and defending behaviors such as injection attack and code tampering, and the security of encrypting the file is improved.

Alliance chain system based on smart contract

The invention provides an alliance chain system based on a smart contract. The alliance chain system comprises a trusted policy management center, a consensus node and a plurality of organizations, each organization is respectively connected with the consensus node and the credible strategy management center, and the consensus node is connected with the credible strategy management center; the organizations comprise credible nodes and common nodes, and the credible nodes and the common nodes in any organization are connected with each other; wherein the trusted policy management center, the consensus node and the trusted nodes all comprise trusted platform control modules; the credible strategy management center generates a system strategy; the trusted node creates and calls an intelligent contract, wherein the intelligent contract comprises a corresponding contract strategy; the common node calls the smart contract; and the consensus node judges whether creation and calling of the smart ...
